Need an improved race livery texture

Heyo skin painters, I hope someone can help me out here. I have worked on an Audi 90 IMSA GTO around christmas but never finished it, I wanted to put the finishing touches on it now, the race liveries however are sadly only 1024x1024 pixels, which doesn't look that good up close. Would be nice to have at least 2048x2048 liveries. They both are pretty much identical except for the numbers (4 and 5) and driver names. Hope someone can help out
